Rodin Workshop 2026

13th Rodin User and Developer Workshop

The 13th Rodin User and Developer Workshop, May 18th, 2026, Tokyo, Japan * Hybrid event *

Event-B is a formal method for system-level modelling and analysis. The Rodin Platform is an Eclipse-based toolset for Event-B that provides effective support for modelling and automated proof.

The platform is open-source and is further extendable with plug-ins. A range of plug-ins have already been developed.

The 13th Rodin workshop will be collocated with the FM 2026 Conference,.

The purpose of this workshop is to bring together existing and potential users and developers of the Rodin toolset and to foster a broader community of Rodin users and developers.

For Rodin users the workshop will provide an opportunity to share tool experiences and to gain an understanding of on-going tool developments.

For plug-in developers the workshop will provide an opportunity to showcase their tools and to achieve better coordination of tool development effort.

Proceedings is available [will be availble here].
